Abstract

Abstract

En 中文
Millimetre-wave multiple-input multiple-output (MIMO) radar has many advantages such as flexible adaptability to complex environments and high detection accuracy. Among the numerous waveforms of MIMO radar, DDMA has a wide application prospect benefiting from its technical superiority. In this paper, we use empty-band based Doppler division multiple access (DDMA) to resolve the ambiguous velocity and then for further signal separation. But there remains a problem of separating multiple targets at the same distance. Thus, we propose a frame-interleaved binary mask method for the separation of empty-band DDMA signals. Simulation results demonstrate that our proposed method can effectively separate empty-band DDMA signals in the same condition.
